Hi, I love your app it's been very useful for school; however I don't undersand why tan(90°) gives me 16331.... when tan(90°) is undefined.. maybe there's something I'm missing, any ideas?

That must be another floating point glitch. It should be undefined, as you say, but it looks like it's calculating a value just off of true 90 degrees. I'll try to fix that for the next version.
